The AI revolution

Artificial intelligence is having a profound effect on economies and society. From production, to services, to healthcare, to pharmaceuticals; to education, to research, to data analysis; to software, to search engines; to planning, to communication, to legal services, to social media – to our everyday lives, AI is transforming the way humans interact. And that transformation is likely to accelerate. But what will be the effects on GDP, on consumption, on jobs, on the distribution of income, and human welfare in general? These are profound questions and ones that economists and other social scientists are pondering. Here we look at some of the issues and possible scenarios.

According to the Merrill/Bank of America article linked below, when asked about the potential for AI, ChatGPT replied:

AI holds immense potential to drive innovation, improve decision-making processes and tackle complex problems across various fields, positively impacting society.

But the magnitude and distribution of the effects on society and economic activity are hard to predict. Perhaps the easiest is the effect on GDP. AI can analyse and interpret data to meet economic goals. It can do this much more extensively and much quicker than using pre-AI software. This will enable higher productivity across a range of manufacturing and service industries. According to the Merrill/Bank of America article, ‘global revenue associated with AI software, hardware, service and sales will likely grow at 19% per year’. With productivity languishing in many countries as they struggle to recover from the pandemic, high inflation and high debt, this massive boost to productivity will be welcome.

But whilst AI may lead to productivity growth, its magnitude is very hard to predict. Both the ‘low-productivity future’ and the ‘high-productivity future’ described in the IMF article linked below are plausible. Productivity growth from AI may be confined to a few sectors, with many workers displaced into jobs where they are less productive. Or, the growth in productivity may affect many sectors, with ‘AI applied to a substantial share of the tasks done by most workers’.

Growing inequality?

Even if AI does massively boost the growth in world GDP, the distribution is likely to be highly uneven, both between countries and within countries. This could widen the gap between rich and poor and create a range of social tensions.

In terms of countries, the main beneficiaries will be developed countries in North America, Europe and Asia and rapidly developing countries, largely in Asia, such as China and India. Poorer developing countries’ access to the fruits of AI will be more limited and they could lose competitive advantage in a number of labour-intensive industries.

Then there is growing inequality between the companies controlling AI systems and other economic actors. Just as companies such as Microsoft, Apple, Google and Meta grew rich as computing, the Internet and social media grew and developed, so these and other companies at the forefront of AI development and supply will grow rich, along with their senior executives. The question then is how much will other companies and individuals benefit. Partly, it will depend on how much production can be adapted and developed in light of the possibilities that AI presents. Partly, it will depend on competition within the AI software market. There is, and will continue to be, a rush to develop and patent software so as to deliver and maintain monopoly profits. It is likely that only a few companies will emerge dominant – a natural oligopoly.

Then there is the likely growth of inequality between individuals. The reason is that AI will have different effects in different parts of the labour market.

The labour market

In some industries, AI will enhance labour productivity. It will be a tool that will be used by workers to improve the service they offer or the items they produce. In other cases, it will replace labour. It will not simply be a tool used by labour, but will do the job itself. Workers will be displaced and structural unemployment is likely to rise. The quicker the displacement process, the more will such unemployment rise. People may be forced to take more menial jobs in the service sector. This, in turn, will drive down the wages in such jobs and employers may find it more convenient to use gig workers than employ workers on full- or part-time contracts with holidays and other rights and benefits.

But the development of AI may also lead to the creation of other high-productivity jobs. As the Goldman Sachs article linked below states:

Jobs displaced by automation have historically been offset by the creation of new jobs, and the emergence of new occupations following technological innovations accounts for the vast majority of long-run employment growth… For example, information-technology innovations introduced new occupations such as webpage designers, software developers and digital marketing professionals. There were also follow-on effects of that job creation, as the boost to aggregate income indirectly drove demand for service sector workers in industries like healthcare, education and food services.

Nevertheless, people could still lose their jobs before being re-employed elsewhere.

The possible rise in structural unemployment raises the question of retraining provision and its funding and whether workers would be required to undertake such retraining. It also raises the question of whether there should be a universal basic income so that the additional income from AI can be spread more widely. This income would be paid in addition to any wages that people earn. But a universal basic income would require finance. How could AI be taxed? What would be the effects on incentives and investment in the AI industry? The Guardian article, linked below, explores some of these issues.

The increased GDP from AI will lead to higher levels of consumption. The resulting increase in demand for labour will go some way to offsetting the effects of workers being displaced by AI. There may be new employment opportunities in the service sector in areas such as sport and recreation, where there is an emphasis on human interaction and where, therefore, humans have an advantage over AI.

Another issue raised is whether people need to work so many hours. Is there an argument for a four-day or even three-day week? We explored these issues in a recent blog in the context of low productivity growth. The arguments become more compelling when productivity growth is high.

Other issues

AI users are not all benign. As we are beginning to see, AI opens the possibility for sophisticated crime, including cyberattacks, fraud and extortion as the technology makes the acquisition and misuse of data, and the development of malware and phishing much easier.

Another set of issues arises in education. What knowledge should students be expected to acquire? Should the focus of education continue to shift towards analytical skills and understanding away from the simple acquisition of knowledge and techniques. This has been a development in recent years and could accelerate. Then there is the question of assessment. Generative AI creates a range of possibilities for plagiarism and other forms of cheating. How should modes of assessment change to reflect this problem? Should there be a greater shift towards exams or towards project work that encourages the use of AI?

Finally, there is the issue of the sort of society we want to achieve. Work is not just about producing goods and services for us as consumers – work is an important part of life. To the extent that AI can enhance working life and take away a lot of routine and boring tasks, then society gains. To the extent, however, that it replaces work that involved judgement and human interaction, then society might lose. More might be produced, but we might be less fulfilled.

Game over or game on? The Microsoft/Activision merger case concludes

In a recent blog post on this site about the Microsoft/ Activision Blizzard merger, the European Commission had just reached a decision to approve the merger subject to remedies, but the investigations in the USA and UK were still ongoing. Since then, the merger has been approved by competition authorities around the world, including in the USA and UK, and thus the merger has gone through.

However, there were some differences in the way the case unfolded under the regulation of these three competition authorities.

The European Commission’s (EC) decision

The European Commission (EC) was the first to give the merger the green light. The EC’s in-depth investigation revealed concerns about the market for the distribution of games via cloud game streaming services. In particular, the concern was related to the possibility that Microsoft might make Activision’s games exclusive to its own cloud game streaming service (Game Pass Ultimate) and restrict access from competing cloud game streaming providers.

The EC argued that this in turn could strengthen Microsoft’s position in the market for PC operating systems, as Microsoft may have an incentive to limit or reduce the quality of the streaming of Activision’s games on PC’s which do not use the Windows operating system.

Thus, while the merger was approved, this was subject to remedies. These remedies included 10-year licensing commitments from Microsoft, as outlined in the EC’s press release:

These licenses will ensure that gamers that have purchased one or more Activision games on a PC or console store, or that have subscribed to a multi-game subscription service that includes Activision games, have the right to stream those games with any cloud game streaming service of their choice and play them on any device using any operating system.

This type of remedy is called a behavioural remedy and often requires the merging firms to commit to taking particular actions post-merger. Unlike structural remedies (which may for example, require the merging firms to sell off an entire business unit), behavioural remedies often require monitoring and enforcement by competition authorities. The EC argued that the deal, with these behavioural remedies, could strengthen competition in the market for cloud gaming.

The Federal Trade Commission’s (FTC) decision

The FTC, in the USA, had similar concerns to those of the EC related to the cloud gaming market. These were outlined in the FTC’s press release:

[The deal] would enable Microsoft to suppress competitors to its Xbox gaming consoles and its rapidly growing subscription content and cloud-gaming business.

The FTC also argued that when Microsoft had previously acquired gaming content, it had made this content exclusive to Microsoft consoles. This could result in higher prices, and reduced quality, choice and innovation. To this end, the FTC appealed in an attempt to block the deal, but the Court ruled in favour of the deal going ahead.

During this time, Microsoft announced that it had committed to keeping Call of Duty on Sony’s PlayStation after the merger, and this likely contributed towards the court’s decision. Hence, the FTC was unsuccessful in its attempt to halt the merger.

The Competition and Markets Authority’s (CMA) decision

The final hurdle remaining for Microsoft, was the CMA’s approval. As outlined in a previous blog post on this site, the CMA’s phase 2 investigation revealed similar concerns about the supply of cloud gaming services (amongst concerns related to the market for the supply of console gaming services, which were later dispelled), and whilst Microsoft offered some commitments similar to those accepted by the EC, the CMA did not deem these to be sufficient to address its concerns and thus prohibited the merger.

The CMA’s published remedies guidance suggests that the regulator has a preference for structural remedies over behavioural remedies. One of the reasons for this is because of the requirement to monitor and enforce the commitments, and this therefore formed part of the CMA’s reasons for not accepting the remedies. Unsurprisingly, Microsoft appealed this decision to the UK’s Competition Appeals Tribunal (CAT), probably partly driven by the fact that the EC accepted similar remedies to those rejected by the CMA. However, Microsoft and the CMA agreed that if the appeal was paused, Microsoft could propose a new deal.

The new deal: did the CMA make a U-turn?

In August 2023, Microsoft submitted a new restructured deal for the CMA to review. As described by the Chief Executive of the CMA, this deal was “substantially different from what was put on the table previously” and was therefore investigated as a separate merger case under the CMA’s phase 1 processes.

The new deal meant that Microsoft would no longer be purchasing the cloud streaming rights held by Activision. Instead, the cloud streaming rights would be sold to an independent third-party game publisher – Ubisoft. This means that Microsoft will not be in control of the cloud gaming rights for Activision’s gaming content (outside of the EEA), and therefore will not be able to restrict its competitors’ access to Activision’s games, which was one of the main concerns outlined by the CMA based on the initial merger proposal. The new deal also opens up the possibility that Activision’s games will be made available on cloud gaming services that run on a non-Windows operating system.

On 13 October, the CMA approved this deal, subject to the cloud gaming rights being sold to Ubisoft, and some subsequent commitments from Microsoft in relation to its relationship with Ubisoft post-merger, as outlined in the CMA’s final report. However, the Chief Executive of the CMA has emphasised that they are unhappy with the way that Microsoft dealt with negotiating the approval of the merger:

But businesses and their advisors should be in no doubt that the tactics employed by Microsoft are no way to engage with the CMA. Microsoft had the chance to restructure during our initial investigation but instead continued to insist on a package of measures that we told them simply wouldn’t work. Dragging out proceedings in this way only wastes time and money.

What’s next in big tech?

While the merger deal has now gone through, the FTC has recently re-opened its case against Microsoft, which will continue to unfold over the next couple of months until December when the case will appear in Court. This means it is possible that the FTC could attempt to undo the merger, though this would be challenging.

In the tech market more broadly, the CMA has recently launched a market investigation into cloud services. While the focus of this blog post was on cloud gaming, cloud services are now increasingly being used by many businesses. The CMA’s issues statement suggests that a key focus of its investigation will be on the ability for customers to switch between cloud service providers. Microsoft is one of the largest providers of cloud services in the UK, and therefore it is inevitable that it will be under scrutiny. Given all three regulators’ recent efforts to ‘crackdown’ on big tech, this is just one of a series of cases that will be interesting to see unfold.

Microsoft’s proposed takeover of Activision Blizzard: CMA’s final ruling.

Effects on competition in the console and cloud gaming markets

Many people in the games industry expected the Competition and Markets Authority (CMA) to approve Microsoft’s proposed takeover of the games business, Activision Blizzard. However, in its final report published on 26 April, the CMA stated that the takeover would result in a substantial lessening of competition (SLC) in the supply of cloud gaming services in the UK. It rejected a behavioural remedy proposed by Microsoft and concluded that the merger should be prohibited.

When analysing the potential impact of this merger, the CMA focused on the following three issues:

  1. How important is the availability of Activision Blizzard’s games for the competitiveness of Microsoft’s rivals in the console and cloud gaming market? If, following the merger, Microsoft used its control over Activision Blizzard to restrict the availability of the games, would this significantly harm the competitiveness of their rivals?
  2. If restricting the availability of the games did harm its rivals, would it be profitable for Microsoft to do so? Do the benefits outweigh the costs? The major benefit for Microsoft is the additional sales this generates as consumers switch to its products to gain access to Activision’s games. The major cost is the forgone sales of the games to their rivals in the console and cloud gaming market.
  3. If it is profitable for Microsoft to limit the availability of the games, would this policy lead to a substantial lessening of competition (SLC) in the console and cloud gaming market? To answer this question the CMA compared the level of competition that would be most likely to occur if the merger were to proceed with the level if the deal were prohibited? In other words, it needed to identify the counterfactual.

In response to the first issue, the CMA judged that restricting access to Activision Blizzard’s games post-merger would significantly harm the competitiveness of Microsoft’s rivals in both the console and cloud gaming markets. However, its judgment on the second issue differed between the two markets. Why was this? One key issue was the difference in the relative market power of Microsoft in cloud vs console gaming.

One common indicator used to analyse the market position of a business relative to its rivals is market share. Using data on revenues generated from the sales of hardware, associated games and subscription services, console gaming market shares in the UK for 2021 were as follows:

  • Sony (PlayStation): 40% – 50%
  • Microsoft (xBox): 30% – 40%
  • Nintendo (Switch): 10% – 20%

Given the important market position of the PlayStation, limiting the ability of its users to purchase Activision games would result in Microsoft forgoing significant sales and revenue. Detailed analysis of the data by the CMA, indicated that the costs outweighed the benefits and so Microsoft did not have a commercial incentive to limit the availability of the games in this market. Therefore, the CMA concluded that the merger would not result in a SLC in the console gaming market. This finding was discussed in more detail in a blog on this website in March 2023.

The CMA judged that Microsoft had a much stronger position in the market for cloud gaming.

Cloud gaming services

Cloud gaming offers consumers a new way of playing graphically complex games. In this sector of the market, the games run on remote servers/data centres and then stream over the internet to the user’s device. The great advantage with this approach is that it enables consumers to play games on less powerful hardware devices such as smartphones, tablets, smart televisions, and standard PCs. Although the market is currently quite small it, has grown significantly over the past couple of years. Some people argue that it has the potential to make a dramatic change to the gaming market in the same way that businesses such as Netflix and Spotify have transformed the film, TV, and music industries.

It is more difficult to judge the relative market position of firms in a new and dynamic market, where things can change very quickly. The use of market share data is less informative but can still offer some insights. To estimate market shares in cloud gaming, the CMA used data on the number of monthly active users (MAUs). The figures for paid services in the UK for 2022 were as follows:

  • xCloud (Microsoft): 70% – 80%
  • PlayStation Cloud Gaming (Sony): 20% – 30%
  • Boosteroid: 0 – 5%
  • Nvidia GFN: 0 – 5%

Data suggest that Microsoft has a much stronger position in this market than in console gaming. There is also evidence that its market position is becoming more dominant. The same market shares for xCloud and PlayStation Gaming in 2021 were 40% – 50% and 50% – 60% respectively.

Given some of the limitations of using market-share data in a new and dynamic market, the CMA analysed other information about the sector to assess Microsoft’s market position. The investigation identified three key factors that could give Microsoft a significant cost advantage over its rivals: cloud infrastructure, the Windows operating system and access to a wide variety of games.

  1. Infrastructure: Microsoft’s ownership of Azure, a major cloud computing platform, could give it a significant cost advantage over its rivals in the future. A rival firm would need to develop it own cloud infrastructure or purchase these services from a third-party supplier.
  2. The Windows operating system: Given that far more games are developed for Windows as opposed to other operating systems, using Windows on a cloud infrastructure system gives a supplier access to large number of games. As it already owns Windows, Microsoft will be able to supply the operating system to its own cloud gaming service at little additional cost whereas its rivals will have to pay a license fee.
  3. Access to a wide range of games: Microsoft already owns twenty-four development studios that produce some very successful games such as Minecraft and Halo. It also has commercial relationships with other third-party developers who produce games for the Xbox console. This gives Microsoft another advantage over many of its rivals.

Given this evidence on Microsoft’s strong market position, the CMA concluded that the benefits to the company of restricting the availability of the games in the cloud gaming market outweighed the costs.

If Microsoft has commercial incentives to restrict the availability of Activision’s games, would this strategy lead to a SLC in the market for cloud gaming? To answer this question, the CMA had to identify the counterfactual: i.e. the most likely outcome in the market if the merger did not proceed. Following detailed analysis of the evidence, the competition authority concluded that Activision was likely to make its games available to different cloud gaming services if the deal did not take place.

Given Microsoft’s (a) strong market position and (b) limited number of relatively small competitors in cloud gaming, the CMA concluded that Microsoft’s commercial incentive to restrict the availability games would lead to a SLC compared to the counterfactual.

Martin Coleman, the chair of the independent panel of experts who conducted the CMA’s investigation, stated that:

Microsoft already enjoys a powerful position and head start over other competitors in cloud gaming and this deal would strengthen that advantage giving it the ability to undermine new and innovative competitors.

In response to these competition concerns, Microsoft offered to supply Activision games to certain cloud gaming services for a 10-year period. However, the CMA concluded that this behavioural remedy was not enough to address the competition issues raised by the merger and recommended that the deal be prohibited.

Microsoft’s immediate response was to appeal the decision to the Competition Appeal Tribunal.

The Federal Trade Commission is currently investigating the impact of the deal in the USA while the European Commission has just completed its investigation in the European Union. On 15 May, the EC announced that Microsoft’s behavioural remedy did fully address the competition concerns identified during its investigation. Therefore, the merger was approved on condition that Microsoft fully implemented the actions outlined in the remedy.

It will be interesting to read the recommendations of the FTC when the final results of its investigation are published later this year.

Microsoft’s proposed acquisition of Activision

Why did a competition authority change its mind on one aspect of this merger?

In January 2022, Microsoft announced its plan to acquire Activision Blizzard for $68.7 billion. Activision Blizzard is one of the largest games publishers in the world and famous for titles such as Call of Duty and World of Warcraft. Sales revenue from Call of Duty: Modern Warfare II was over $10 billion within ten days of its release in 2022. Given Microsoft’s ownership of the Xbox, one of the three devices that dominate the market for gaming consoles, the deal was always likely to raise competition concerns.

Potential competition issues

Following Phase 1 and 2 merger investigations by the Competition and Markets Authority (CMA) a number of competition issues were raised. One particular concern was in the market for gaming consoles and the potential impact of the merger on the future availability of Call of Duty (CoD). Some of the key findings of the initial research undertaken by the CMA were that:

  • Sony’s PlayStation was a much closer rival for the Xbox than the Nintendo Switch, which tends to offer more family-orientated games.
  • PlayStation users spend significant amounts of gametime playing CoD.
  • Game availability is a key factor that influences console purchase decisions.
  • Twenty-four percent of PlayStation users who play CoD stated that they would not purchase future versions of the console if CoD was unavailable on the platform.

These findings suggest that there are commercial incentives for Microsoft to limit the availability of CoD on the PlayStation. For example, the newly merged business could make future versions of the game exclusive to the Xbox – total exclusivity. Alternatively, it could adopt a policy of partial exclusivity. For example, it could only make versions of CoD available on the PlayStation that exclude some of its more popular features.

There are costs to Microsoft of implementing a policy of total or partial exclusivity. For example, 76% per cent of PlayStation users who play CoD stated that they would not switch consoles if future versions of the game were made unavailable. By making CoD exclusive to Xbox users, Microsoft would lose revenue from forgoing potential sales of the game to this group of users. The firm may also suffer reputational damage if there was a social media backlash against an exclusivity decision.

However, these costs of implementing a policy of exclusivity could be outweighed by the potential benefits. These include:

  • The additional sales of consoles as some users switch from the PlayStation to the Xbox to gain access to CoD.
  • the sale of CoD and other games to these additional Xbox users.

To quantify these costs and benefits, the CMA used a financial model that includes information on the amounts of money users typically spend on the Xbox platform and CoD over a five-year period. This ‘lifetime value of customers’ model found that it would be profitable for Microsoft to implement a policy of exclusivity post-merger.

The CMA also noted that in the majority of cases where Microsoft had previously acquired gaming studios, the subsequent release of games had been made exclusive to the Xbox.

CMA findings

Following its analysis of the case, the CMA published its provisional findings on the 8th February 2023. One key finding was that the merger would harm consumers, as it would lead to a substantial lessening of competition in the supply of console gaming services. The CMA argued that the acquisition should proceed only if Activision Blizzard sold off the parts of its business responsible for producing CoD. This is a structural remedy.

Microsoft rejected these findings and argued that the financial modelling used by the CMA was based on inaccurate data. In its formal written response to the competition authority the company argued that:

  • The potential gains from a policy of exclusivity had been calculated over a five-year period whereas the costs (i.e. the forgone sales of CoD) had only been calculated over a one-year period. More accurate analysis should compare both the potential gains and losses over a five-year period.
  • When more recent data are used to calculate the amounts of money users typically spend on the Xbox platform and CoD over a five-year period, the figure is lower than in the original work by the CMA.

Revised CMA findings

Having adjusted its analysis to take account of these criticisms, the CMA published an update to its Provisional Findings on 24th March 2023. In this update the competition authority stated that:

The analysis now shows that it would not be commercially beneficial to Microsoft to make CoD exclusive to Xbox following the deal, but that Microsoft will instead still have the incentive to continue to make the game available on PlayStation.

Therefore, just six weeks after publishing its Provisional Findings the CMA changed its conclusion and stated that the merger would not result in a substantial lessening of competition in the market for the supply of console gaming services in the UK.

In response to these changes an ex-CMA lawyer stated that:

This is extremely unusual. Restating your provisional findings is something ‘you would rather die than do’.
It is important to remember that the investigation by the CMA also raised concerns about the impact of the acquisition on competition in the cloud gaming market. These concerns remain unaffected by these updated findings and a final report will be published by the CMA at the end of April.

Competition authorities from 16 different countries/regions are also investigating the deal, including the Federal Trade Commission in the USA and the European Commission. It will be interesting to see if these authorities agree on the potential impact of the merger on competition.

A four-day week – a solution to sluggish productivity growth?

In two previous posts, one at the end of 2019 and one in July 2021, we looked at moves around the world to introduce a four-day working week, with no increase in hours on the days worked and no reduction in weekly pay. Firms would gain if increased worker energy and motivation resulted in a gain in output. They would also gain if fewer hours resulted in lower costs.

Workers would be likely to gain from less stress and burnout and a better work–life balance. What is more, firms’ and workers’ carbon footprint could be reduced as less time was spent at work and in commuting.

If the same output could be produced with fewer hours worked, this would represent an increase in labour productivity measured in output per hour.

The UK’s poor productivity record since 2008

Since the financial crisis of 2007–8, the growth in UK productivity has been sluggish. This is illustrated in the chart, which looks at the production industries: i.e. it excludes services, where average productivity growth tends to be slower. (Click here for a PowerPoint of the chart.)

Prior to the crisis, from 1998 to 2007, UK productivity in the production industries grew at an annual rate of 6.1%. From 2007 to the start of the pandemic in 2020, the average annual productivity growth rate in these industries was a mere 0.5%.

It grew rapidly for a short time at the start of the pandemic, but this was because many businesses temporarily shut down or went to part-time working, and many of these temporary job cuts were low-wage/low productivity jobs. If you take services, the effect was even stronger as sectors such as hospitality, leisure and retail were particularly affected and labour productivity in these sectors tends to be low. As industries opened up and took on more workers, so average productivity fell back. In the four quarters to 2022 Q3 (the latest data available), productivity in the production industries fell by 6.8%.

If you project the average productivity growth rate from 1998 to 2007 of 6.1% forwards (see grey dashed line), then by 2022 Q3, output per hour in the production industries would have been 21/4 times (125%) higher than it actually was. This is a huge productivity gap.

Productivity in the UK is lower than in many other competitor countries. According to the ONS, output per hour in the UK in 2021 was $59.14 in the UK. This compares with an average of $64.93 for the G7 countries, $66.75 in France, £68.30 in Germany, $74.84 in the USA, $84.46 in Norway and $128.21 in Ireland. It is lower, however, in Italy ($54.59), Canada ($53.97) and Japan ($47.28).

As we saw in the blog, The UK’s poor productivity record, low UK productivity is caused by a number of factors, not least the lack of investment in physical capital, both by private companies and in public infrastructure, and the lack of investment in training. Other factors include short-termist attitudes of both politicians and management and generally poor management practices. But one cause is the poor motivation of many workers and the feeling of being overworked. One solution to this is the four-day week.

Latest evidence on the four-day week

Results have just been released of a pilot programme involving 61 companies and non-profit organisations in the UK and nearly 3000 workers. They took part in a six-month trial of a four-day week, with no increase in hours on the days worked and no loss in pay for employees – in other words, 100% of the pay for 80% of the time. The trial was a success, with 91% of organisations planning to continue with the four-day week and a further 4% leaning towards doing so.

The model adopted varied across companies, depending on what was seen as most suitable for them. Some gave everyone Friday off; others let staff choose which day to have off; others let staff work 80% of the hours on a flexible basis.

There was little difference in outcomes across different types of businesses. Compared with the same period last year, revenues rose by an average of 35%; sick days fell by two-thirds and 57% fewer staff left the firms. There were significant increases in well-being, with 39% saying they were less stressed, 40% that they were sleeping better; 75% that they had reduced levels of burnout and 54% that it was easier to achieve a good work–life balance. There were also positive environmental outcomes, with average commuting time falling by half an hour per week.

There is growing pressure around the world for employers to move to a four-day week and this pilot provides evidence that it significantly increases productivity and well-being.
